With the widespread application of 4G and the rapid advancement of 5G, a new generation of IoT technologies represented by NB-IoT, eMTC, etc. have emerged. At present, the scale of the physical-to-physical connection is expanding rapidly, and the connection application is changing with each passing day. It can be said that the Internet of Things technology has been deeply embedded in multiple vertical industries and is widely used in the following important fields:

One. Industrial energy: covering smart meter reading, smart switches, product process management, etc .;

two. Transportation industry: covering smart parking, bike sharing, etc .;

three. Smart home

four. Remote health management;

Fives. Smart city: covering smart street lights, air detection, smart manhole covers, etc .;

six. Smart agriculture: covering smart greenhouses, animal traceability, forestry data collection, etc .;

Seven. Financial industry: financial leasing, cash box monitoring, etc .;

Eight. other

As the Internet of Things technology is deeply infiltrating various industries in the society, the application of Internet of Things technology in different fields also faces pain points in different industries. In this regard, Communication World Network will analyze and analyze one by one. Last time, "Application scenarios and pain points of the Internet of Things in the field of intelligent meter reading" written by the author received a lot of reader feedback and some vertical media reprints of the Internet of Things, which played a certain communication value. The interpretation this time will focus on smart switches and discuss their application scenarios and pain points in the Internet of Things.

At present, the main application scenarios of the Internet of Things in the field of smart switches are mostly in the areas of oil leakage monitoring, plant area / warehouse management, and so on.

Oil Spill Monitoring

As everyone knows, oil transportation vehicles need to travel long distances. Oil pipelines are widely distributed in inaccessible areas, and they are vulnerable to oil stealing threats by oil consumers, or damage caused by long-term use, causing oil leakage problems.

If the intelligent switch is installed at the oil outlet of the tanker truck, the important node of the oil pipeline, etc., it can realize the precise management of the oil extraction process. Because only authorized personnel can open the switch, such as the destination oil and gas station staff, gas station operators, line maintenance workers.

At present, smart switch companies tend to use the NB-IoT network in the Internet of Things application, and automatically report opening and closing information every time. For example, the smart switch solution launched by China Mobile will automatically lock the smart switch when unauthorized personnel attempt to open the oil circuit breaker, violently tear down, or drill holes, generate alarm information and abnormal records, report to the platform, and synchronize Trigger local alarm devices such as siren and lights.

Of course, just a local alarm is not enough. It is also necessary for the platform to send the alarm information to the handheld terminal of the fuel manager, and to record the abnormal event log to provide assistance for subsequent processing. Through the above dual alert mechanism, the difficulty of illegal acts is increased.

Plant area / warehouse management

Industrial plants generally occupy a large area, far from the city, and a large number of core assets are placed inside the plants. Generally, enterprises will arrange multiple administrators to manage the access control. Therefore, whether it is to open or lock the door, or the daily personnel and vehicle entry and exit management, it is relatively hard, labor costs are high, and there are certain safety risks.

Sub-scenario 1: For smart switch requirements, it is generally necessary to meet the needs of the plant manager to unlock or unlock the door by remote control using a handheld terminal. In addition, the administrator of the smart switch platform can set the user role to assign unlocking and unlocking permissions to the plant administrator, and decentralize and rotate the permissions, which can realize the upgrade of the factory gate management from the traditional "pipe key" to "pipe authority". . In addition, it is required that the intelligent switch platform can be docked with the inspection platform to achieve regular inspections of the warehouse in the factory area;

Sub-scenario 2: When the smart locks deployed on the gates of the factory area detect external impacts, abnormal vibrations, and windfall profits, they can automatically send alarm information to the business platform through the network and send them to the plant manager. Corresponding measures

Sub-scenario 3: For the smart switch management platform, the administrator can set the smart lock to match the designated vehicle, and identify the vehicle through short-distance short message or video surveillance. The smart lock is automatically opened or closed automatically when the recognition is successful, and the entry and exit records are automatically transmitted back. To the platform, which in turn can reduce the workload of frequent opening and closing of the gate by the plant manager with the key.

In addition, the industry has the following scenarios for smart switch application requirements, such as:

Cabinet security protection: Provides functions such as automatic unlocking and unlocking, and abnormal alarms. The file cabinet administrator or the holder of the cabinet can set the locking or unlocking of the smart lock through mobile phone APP scanning, etc., to obtain the information of brute force cracking in time, effectively reducing the chance of losing files or luggage;

Indoor access control management: Provide access control management, resource management, equipment protection and other functions to important areas such as computer rooms and archives. Regional managers can directly control the opening and closing of each door through the business platform portal or mobile phone APP, or set the access mode of the door to authorize the opening and closing of each door to achieve unified management of the area;

Optical switch box management: Provides functions such as monitoring the switch box status, alarming abnormal conditions, and recording opening and closing logs. Operation and maintenance personnel can check the status of the door lock of the optical switch box at any time through the mobile phone APP, and record the door opening and closing information brought by the normal maintenance of the equipment. When the cabinet encounters man-made damage or accidental collision, the operation and maintenance personnel obtain the abnormal alarm in time, and contact the personnel to go to the site for disposal.

Industry pain points in the field of smart switches

The traditional switch product use methods include artificially equipping keys, arranging patrol personnel, increasing the firmness of the lock itself, and setting up video surveillance probes. At present, these methods generally face many problems such as difficulty in key management and control, no monitoring of status, difficulty in inspection management, high labor cost, and the need to dispose after the fact, and more urgent solutions need to be introduced.

Among them, in the process of industrial product storage and transportation, traditional locks do not have the functions of unlocking personnel identification, remote control, positioning, etc. Supervision mainly relies on handover of personnel, which leads to theft, destruction, and guardianship of illegal personnel from time to time, which brings economic benefits to enterprises. loss. For example, if an oil field is stolen for crude oil every year, it loses more than 100 million yuan. In a certain province, a transportation driver stole oil products, which caused 100 oil tankers to malfunction, and the economic loss exceeded 10 million yuan.

Broad application prospects for smart switches

The switch product is used to manage and control the state of the controlled object, and reflects the authorized user's right to view, use, and dispose of the controlled object. Authorization forms can be keys, account numbers, special equipment, biometrics, etc. Switch products vary widely, such as car locks, door locks, container locks, express parcels, oil pipeline valves, store seals, etc. Therefore, switch products have a wide range of application requirements in many industries such as industry, energy, municipal, and telecommunications.

At present, companies including China Mobile, Xiaowei, Open Source Intelligence, April, etc. have launched a variety of smart switch solutions. For example, with the help of NB-IoT technology, China Mobile has the characteristics of low power consumption, low cost, support for massive connections, and is suitable for small data volumes and non-mobile services. The smart switch solution developed by China Mobile combines smart locks, business management platforms, Intelligent devices such as industry terminals provide comprehensive user services such as access control, status monitoring, and abnormal alarms for products with switching characteristics such as doors, valves, and cabinets.

Since most industrial energy companies are asset-heavy companies, they need to invest huge manpower and resources to achieve asset management. At present, the IoT companies involved in the field of smart switches mainly include chip / module manufacturers, smart hardware manufacturers, and third-party application providers.
